olL-supeLY SYSTEM.

sPncIFIcATIoN forming part of Letters Patent No. 748,727, dated January 5, 1904. Application iiled September 2, '1902- Serial No. 121,805. (No model.)

To atl whom it may concern:

Be it known that I, HANS C. HANsoN, a citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Oil-Supply Systems; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to new and useful improvements in a system for supplying gasolene or other hydrocarbon oils to the burners throughout a building for lighting or other purposes.

The object of the invention is to provide a system of this character which is simple and safe in operation, in which the supply or storage tank may be refilled Without interfering with the pressure throughout the system, and one which will conform to all the requirements of the lire underwriters.

With these and other objects in view the invention consists incertain features of construction, combination',l and arrangement of parts, which will be hereinafter more fully set forth, and particularly pointed out inthe appended claim.

In the drawing grammatical sectional View through the improved apparatus.

Referring more particularly to the drawing, the numeral 1 denotes a supply or storage tank of any desired construction and capacity provided with the filling inlet or opening 2, which is closed by the screw-cap 3. 4 designates a force-pump located Within said tank and having its operating-handle 5 projecting through the top of the tank upon the outside thereof. The pump may be of any Well-known or `preferred type and is provided with the usual check-valves 6 and 7. The inlet to the pump is in the lower end of the casing, which rests upon the bottom of the tank, and the outlet is through the vertical 'pipe 8, which passes through the top of the tank.

A short horizontal pipe 9 connects the up- I have illustrated a dia-V 12, which' divides the same into two compartments or chambers, the lower one for oil and the upper one for compressed air. A small opening or aperture 13 in said partition allows the' compressed air to enter the oilchamber as the oil lowers.

The air-chamber is adapted to be filled with compressed air by means of a pump 14 of any desired construction. A pipe 15 connects said pump and the air-chamber of the tank 11 and is provided with abut-on' valve 16. The pressure-tank 11 is also provided with a pressure-gage 20 for the purpose of indicating the amount of pressure in said tank and throughout the system.

The oil-chamber of the pressure-tank 11 and the storage-tank l is adapted to contain the gasolene or other hydrocarbon Aoil which is to be distributed to the burners through- 4out the building or premises. The servicepipe 17, preferably of iiexible copper tubing, is connected with the upper end of the vertical pipe 10 and leads to the illuminating or heating burners. (N ot illustrated.)v A cutoft valve 18 in the upper end of the pipe 10 permits the supply of gasolene to be cut off from the'burners, and a cut-oft valve 19, 1ocated in the upper end of the pipe 8, prevents the return of the gasolene to the storagetank 1.

In the operation of the apparatus the storage-tank 1 is filled through the inlet-opening 2 to any desired degree. The force-pump l is then operated to force the gasolene up the pipe 8 through valve 19, the same having been opened through pipes 9 and 10 into the oil-chamber of the pressure-tank 11. The said chamber is adapted to contain the amount of oil allowed by the tire underwriters. the measuring-chamber is being filled with oil or gasolene, the pump 4 can be operated with comparative ease, the opening 13 permitting the escape of the air displaced by the oil in the measuring-chamber into the upper portion of the tank 11. As soon, however, as the measuring-chamber becomes full further operation of the pump 4 is attended with difliculty, owing to the limited capacity of the opening 13 as compared with that of the While ICO pump. Hence the partition 12 serves, practically by the increased labor of the pump 4c, to indicate when the measuring-chamber is full, and thereby to limit the amount of gasolene entering the measuring-chamber. The valve 19 is closed when the hard working of thev pump 4 indicates that the oil-measuring chamber has been filled. The air-pump 14 is then operated to force air through the open valve 16 into the air-chamber until the desired pressure, as indicated on the gage 20, has been reached. The air-valve 16 is then closed to prevent the leakage of air, and the pressure in the tank 11 upon the gasolene will force the same up through the servicepipe to the burners.

It will be noticed that the storage-tank may be refilled at any time without affecting the.

pressure throughout the system, and hence without turning out the lights, and that only a definite amount of oil can be forced into the pressure-tank at one time, and it Will be further noted that in filling the pressuretank the air is not permitted to escape, and hence considerable time and labor is saved.

It vwill also be observed that by the peculiar construction and disposition of the several pipes 8, 9, 10, and 17 the pipe 10 is made to serve the twofold function of a conductor to supply the oil-chamber of the pressure-tank 11 with oil from the reservoir 1 and also to serve as an outlet to discharge the oil under pressure into the service-pipe 17, the iiow of oil being controlled through the medium of the two valves 18 and 19. By this construction the apparatus is considerably simplified, and the use of separate pipes for the supply and discharge of oil to and from the tank 11 avoided.

From the foregoing description, taken in connection with the accompanying drawing, the construction, operation, and advantages of the invention will be readily apparent, it is thought,without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention. v

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In apparatus of the class described,the cornbination of a storage-tank, a tank l1 having a partition 12 therein, provided with a minute opening 13, said partition forming an airchamber in the upper portion of said tank 1l, and an oil measuring chamber in the lower portion of said tank, a pump to force oil from the storage-tank into the oil-measuring chamber of the tank l1, a service-pipe leading from' the said oil-measu ring tank, and means to supply air, under pressure, to the air-chamber of the tank 11 to force the oil from the oil measuring chamber thereof through the service-pipe.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HANS C. HANSON.
